RE: [leaf-user] Is my NIC the bottleneck?
Hi, 768Kb/s = 96KB/s or 93KB/s depending on what your ISP considers a Kilo. I have 1024 over 256 cable, I very VERY rarely see one connection hit more than 70. If I want a fast download, I use Getright and use 3 or 4 different sources. Does anyone else think that all this massive increase in downstream by ISPs (as a marketing tool) is outstripping the resources of the poor old creaky internet? That's just practical thinking though, I don't know any technical reasons you could be running slow.

Re: [leaf-user] Is my NIC the bottleneck?
Your ISP's theoretical 768 Kilo bps compared to your NIC's theoretical 10 Mega bps. Me thinks your 10Mb NIC is not guilty. Do you run your DSL modem as a modem only, or does it do DHCP, DNS and firewall as well? Gus [EMAIL PROTECTED] wrote on 15-04-2004 00:10:31: pn] I'm still running E2B on a P166.

RE: [leaf-user] Is my NIC the bottleneck?
768 Kb/s= ~ 70 kB/sec. You have to taken into account the overhead in the packets which roughly is a factor 10 to translate Kb/s to kB/s. I have a cable connection which is much faster (here in Holland at least) than ADSL and regularly have download speeds of 120 - 150 kB/s.

Re: [leaf-user] Is my NIC the bottleneck?
You shouldn't be, because you were right that there's a bottleneck, you just missed what the bottleneck is. A 768k T-1 or Cablemodem line is going to give you around 90-95Kbytes/sec on a download, whereas your DSL is only turning out around 70Kbytes/sec. The reason for this is pretty straightforward: DSL uses ATM connections between the Central Office DSLAM and the ISP's router. Since ATM only works in packets 53 bytes large, a packet of 1500 bytes gets chopped up into a bunch of other packets, each with it's own control and error markers, and doesn't actually get reassembled until it arrives at the DSL modem. It's worse, too, if you've got PPPoE, as that adds in it's own overhead. The net result is, if you've got a DSL line of speed X, and a Cable line of speed X, then as long as the cable line isn't on an overloaded cable node, the cable line will be faster, because it doesn't have to convert to a half-dozen different Layer 2/3 Protocols along the way. Oh, and yes, some DSL modems do have firewall/NAT routers built in these days, but they tend not to work too well for gaming applications. George Peter Nosko wrote: pn] Thanks, all.

Based on the numbers you report, there is no bottleneck that needs an explanation ... or at worst a very small one. 70something KB/sec (big B = bytes, the way clients usually report transfer speed) translates to something between 560 and 640 Kbps (small b = bits, the measure uses for DSL speed). That discrepancy is too small to need explaining, when you remember that there is also packet overhead and such to allow for (my rule of thumb is to allow 10% of capacity for this). If there is any residual problem to be explained, you will need more exact numbers to detect it. --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

Re: [leaf-user] Is my NIC the bottleneck?
I have Bering-uClibc 2.1 setup in a 486/66 with 16MB. With two ISA (SMC 8216C) 10M cards I have a TESTED ~7M/s download speed from a company internal FTP server. With 100M connection I was able to download (without the FW in the middle) 20M/s. Both tests were done in a ethernet network without ADSL. So this will prove that almost all ADSL speeds can be handled with a slow 486 level PC. PC was actually ICL C4/33V with 25Mhz SX processor and a 66Mhz math co-processor. Std. floppy version used without tweaking. Home ADSL connection is 1M/512K and I get download speeds of 110K/s normally from university servers near me -Marko Peter Nosko wrote: pn] Thanks, all.

Hello Peter, Nice name ;-) Subject: [leaf-user] Is my NIC the bottleneck? pn] I'm still running E2B on a P166. I have 768K SDSL, and my leaf box is connected to the DSL modem I know it's already resolved, but I recommend using DSLReports's speed test for this kind of thing. Test a desktop from behind the LEAF server network, then connect it directly to the DSL line and test again. Using this method you can see if there is a bottleneck in the router. I usually run the test 3 times to get a nice average.
